You can change your air ticket FOR a later one.或者：
You can change your air ticket TO a later date.
語(yǔ)法：change A for B-------把A換成B請(qǐng)問(wèn)用for和to有什么區(qū)別嗎？你好。有啊，for 指的是同類物體之間的交換。to指的是由一個(gè)狀態(tài)到另外一個(gè)狀態(tài)，to a later date指的是“由票子轉(zhuǎn)向時(shí)間”，而a later one中的one仍然指代ticket. 我希望，你已經(jīng)明白了。
